McCain To Appear On SNL

John McCain is set to appear on NBC's "Saturday Night Live" just three days before the presidential election. Aides say the Republican presidential candidate will make a detour from battleground states to the late-night weekend show that has been a must-watch for many during the political season.

Earlier this month, McCain running mate Sarah Palin and her impersonator, Tina Fey, earned "Saturday Night Live" its best ratings in 14 years. Palin's guest shot had been widely anticipated since Fey began imitating her a month ago. McCain last appeared on the show in May, after clinching the nomination and while the Democratic primary continued. McCain hosted "SNL" in 2002.

It may seem risky for McCain to appear on SNL just three days before the election, but his previous appearances have been well-received.
